How to convert metric horsepower to horsepower
One metric horsepower equals 0.98632 horsepower, so multiply the number of metric horsepower by 0.98632:
hp = PS × 0.98632
PS = hp ÷ 0.98632 (1 hp = 1.0139 PS)
Example: 75 PS → 75 × 0.98632 = 73.974 hp.
Going the other way, divide by 0.98632, or multiply by 1.0139; the horsepower to metric horsepower converter does it for you.
